Which statements describe velocity and acceleration? Check all that apply.
Tom [10]

Velocity is defined by rate of change in the position

which we can also write as

v = \frac{ds}{dt}

while acceleration is defined as rate of change in velocity

a = \frac{dv}{dt}

so acceleration and velocity both are rate of change in position and rate of change in velocity with respect to time respectively

out of all above statement the correct answer must be

<u>Acceleration equals change in velocity divided by time. </u>

Answer:

HELLO! I WILL EXPLAIN WHY GOLF BALLS HAVE DIMPLES.
